-Determines whether the encryption option is supported on a remote telnet server.  Some systems (at least FreeBSD) implement this option incorrectly, leading to a remote root vulnerability (FreeBSD-SA-11:08.telnetd). This script currently only tests whether encryption is supported, not for that particular vulnerability.
